Setting the Log Level
Log levels determine the amount of information delivered in a log. Logs can have one of five levels of
detail. A detailed log-level setting creates larger log files and has a greater impact on system
performance than an abbreviated log-level setting. A detailed log-level setting includes all the messages
contained in the abbreviated log-level settings, plus additional messages. As the level of detail increases,
system performance decreases.

Note
You can specify different logging levels for each log type.

Log Levels
Log Level
Description
Critical
Only errors are logged. This is the most abbreviated log-level setting. At this log level,
you cannot monitor performance and important appliance activities; however, the log
files do not reach maximum size as quickly as they do at a detailed log level. This log
level is analogous to the syslog level Alert.

Warning
All system errors and warnings are logged. At this log level, you cannot monitor
performance and important appliance activities. The log files reach maximum size more
quickly than they do at the Critical log level. This log level is analogous to the syslog
level Warning.

Information
Second-by-second operations of the system are logged. For example, connections
opened and delivery attempts are logged. The Information level is the recommended
setting for logs. This log level is analogous to the syslog level Info.
opened and delivery attempts are logged. The Information level is the recommended
setting for logs. This log level is analogous to the syslog level Info.
Debug
More detailed information is logged than at the Information log level. Use the Debug
log level when you are troubleshooting an error. Use this setting temporarily, and then
return to the default level. This log level is analogous to the syslog level Debug.

Trace
All available information is logged. The Trace log level is recommended only for
developers. Using this level causes a serious degradation of system performance and is
not recommended. This log level is analogous to the syslog level Debug.
